Definitions
- the present invention relates coating of a thread and, more particularly, coating in form of dyeing said thread with a liquid, such as a liquid comprising ink.
- Devices for embroidering a medium, such as cloth, in accordance with a design generated using a personal computer are known. Such devices are advantageous in that they make it easy to embroider a complex design.
- the color of the embroidered design depends on the color of the thread. Therefore, when embroidering is carried out using different colored threads, the thread used in the apparatus must be changed each time a different color is to be embroidered. To change the thread, the thread currently in the apparatus must be cut and removed, and another thread having a different color must be threaded in the apparatus and passed through the hole of an embroidery needle. This slows down the embroidery operation and makes it more costly.
- Embroidery devices for industrial use and sewing machines capable of embroidering are known.
- it is necessary to change an upper thread corresponding to the requested color and it is necessary to design the embroidery pattern taking into account the limitations of the embroidery machine and available threads, and then to embroider with these available threads by exchanging the upper thread, as needed.
- a great deal of time and work is required to embroider in different colors using this technique.
- the colors are limited to the number of threads used, and therefore it is cumbersome to embroider in a large number of colors. For example, when embroidering in colors varying continuously from dark green to yellow, it is necessary to provide threads of numerous colors and change them in accordance with the desired color, and therefore the ability of such embroidery techniques to express color variations is limited.
- US 6, 189,989 B l discloses a printing device aiming to mitigate at least some of the above mentioned problems by an ink j et printing apparatus having a station for dyeing a thread for embroidering by discharging ink onto the thread from an ink j et head.
- a printing controller controls the amount of ink discharged per unit time onto the thread according to the speed of the relative movement of the thread and the ink j et head.
- the device is complex and the ink j et head provides unsatisfactory ink coverage of the thread. It is desirable to obtain as small droplets as possible, to obtain an optimized result. Therefore, an ink jet head ink nozzle needs to be sufficiently small.
- a small nozzle is needed to maintain ink inside ink jet head when no ink discharge is wanted. Further, the larger the nozzle diameter, the larger the discharged droplets become, which eventually lead to leakage of ink.
- a small ink jet nozzle is typically also accompanied by technical problems, such as increased risk of clogging, leading to the risk of uneven ink distribution, and short life span and/or costly. All in all, this jeopardizes the precision of the ink distribution, which is vital for a thread coloring thread consuming machine, since failure in this respect leads to wrong color appearing on the wrong position.
- An object of the present invention is to provide a novel device for applying liquid, such as ink, to a single thread as said thread moves relative to the device along a path of movement, which device is improved over prior-art devices of the type discussed above.
- a particular obj ect of the present invention is to provide a novel coating device for dynamically applying liquid, such as ink, to a single thread for a thread consuming device as said thread moves relative to the coating device along a path of movement, which coating device is improved over prior-art devices of the type discussed above.
- liquid such as ink
- a particular obj ect of the present invention is to provide a novel coating device for dynamically applying ink to a single thread for an embroidery machine as said thread moves relative to the coating device along a path of movement, which coating device is improved over prior-art coating devices of the type discussed above.
- a particular object of the invention is to provide such an improved coating device, providing a better ink coverage of the thread.
- Another obj ect is to provide a less complex coating device.
- Another object is to provide a coating device allowing for decreased risk of clogging and improved exactness of ink distribution.
- Another obj ect is to provide a coating device with increased life span.
- a coating device handles application of ink to a thread and is typically fitted into a thread-consuming device comprising other machine elements, such as means for feeding the thread and means for embroidering using the thread.
- a coating device is suitable for dynamically applying ink to a single thread for embroidery as said thread moves relative to the coating device along a path of movement.
- the coating device is configured to apply ink to said thread by means of an electrospraying unit comprising at least one emitter, thread guiding means, ink supply means, voltage supplying means, counter electrode means and an ink flow controller.
- the voltage supplying means is arranged to supply a variable voltage or a modulated voltage, such as an alternating voltage.
- Each respective emitter is suitable for discharging ink from a respective discharge edge, such as a discharge tip or a discharge orifice, towards the thread in a discharge direction, such that a respective discharge zone is formed.
- the thread guiding means is configured to guide the thread through each respective discharge zone.
- the ink supply means is suitable for supplying ink to said at least one emitter, and the voltage supplying means is configured to provide an electric potential between the at least one emitter and the counter electrode means.
- said emitter and said at least one counter electrode means are configured such that an electric field is created between each respective emitter and the counter electrode means to obtain the discharge zone of each respective emitter.
- the ink flow controller is configured to control the ink supply means and the voltage supplying means in response to a control signal for controlling ink output.
- the coating device comprises a diversion electrode means configured to affect the path of movement of emitted ink by means of at least one electric field.
- the diversion electrode may accomplish by-passing of undesired drops of liquid from the flow path towards the thread.
- the first set of droplets from the emitter may be of unknown or unwanted size or potentially contaminated, and thus being undesired to hit the thread.
- the diversion electrode may also be used to direct droplets towards the thread, by alternating its potential in comparison with its setting during by-passing mode. In this way mechanical alignment may be avoided. It is also possible to let the diversion electrode alternate in potential or being applied with a potential sequentially to by-pass droplets passed the thread or to allow droplets to reach the thread.
- the diversion electrode may also be positioned such that it may trap "escaping" droplets.
- Such a coating device makes it possible to dynamically adjust the direction of discharge of ink and/or the shape of the discharge zone. This in turn leads to lower requirements on mechanical tolerances of the guiding means and thus provides for a less expensive and less complicated coating device.
- said coating device comprises a plurality of emitters arranged in a monolithic block. This provides for improved precision of ink application to the thread.
- a plurality of emitters is arranged in series along the path of movement of the thread. This makes it possible to use multiple emitters, thereby providing improved ink coverage. Also, it provides a simple and inexpensive arrangement that makes it possible to hit the thread with ink from all around the thread in the case of threads that are twisting/rotating along their respective longitudinal direction.
- the one or more emitters are arranged perpendicularly relative the path of movement of the thread. This brings the advantage that the degree of coverage is increased, since the ink typically hits the thread more symmetrically.
- shielding means are provided between the emitters.
- the shielding means are configured to electrostatically shield the discharge zones from each other. This promotes independent operation of adjacent emitters, since charged droplets from one emitter, or the emitters respective electrical field, will not affect the performance of other emitters.
- the shielding means is configured to be connected to electric ground. This arrangement makes is possible to continuously remove excess charges from ink droplets hitting the shielding means.
- each respective emitter is coated with a hydrophobic material.
- the hydrophobic coating prevents ink from wetting over outer surfaces of the emitter, which in turn is advantageous since fluid on the outer surface affects the droplet size and frequency of emission of droplets, and also the direction and stability of droplets thereby making it difficult to control ink discharge.
- the at least one emitter comprises a capillary tube with a central passage defining the discharge edge, which in this embodiment comprises a tip with an orifice.
- the capillary tube is commonly available as such, and used in a coating device according to the invention it makes it possible to lower production costs while maintaining high precision. Further, the capillary tube consumes very little space and therefore provides for a compact design of said coating device. Still further, the capillary tube allows for a capillary nozzle having low risk of clogging, due to its relatively large diameter, thus improving life span and exactness of ink distribution.
- the at least one emitter comprises a plate with a thorough hole defining the discharge orifice.
- the plate is easy to manufacture with high precision at low cost. Further, the plate makes it easy to connect the emitter to the voltage supplying means. Also, several emitters may be integrated into a monolithic construction in an inexpensive manner by simply making the plate slightly bigger and providing further holes.
- each emitter is coupled to an individual ink supply means comprised in said ink supply means.
- an extractor electrode is provided adjacent each respective discharge orifice.
- the extractor electrode promotes discharge of ink from each respective emitter.
- the voltage supplying means is configured to provide a potential between each respective emitter and the extractor electrode.
- the extractor electrode is plate- shaped and has a central through hole aligned with the discharge orifice. This brings an advantage in that the plate is easy to manufacture with high precision at low cost. Further, the plate makes it easy to connect the extractor electrode to the voltage supplying means. Also, several extractor electrodes may be integrated into a monolithic construction in an inexpensive manner by simply making the plate slightly bigger and providing further holes.
- the plate-shaped extractor electrode is arranged substantially perpendicular to the discharge direction. This brings an advantage in that that it promotes a symmetric discharge pattern, which in turn increases the degree of coverage and provides for a more even ink covering of the thread.
- the plate-shaped extractor electrode comprises a multitude of layers, such as two or three layers, said layers being arranged transversally to the through hole.
- the different layers may have different polarity, such that the polarity of the layer comprising the side facing the substrate, i.e. the thread, for example may be of a positive potential while the layer comprising the side facing the emitter is of a negative potential, when the emitter is positively charged.
- the liquid being discharged from the emitter, and thus having the same potential as the emitter may be kept from being attracted to the extractor electrode, and will continue towards the substrate, i.e. the thread.
- the electrospraying unit is provided with a thread contacting means configured to provide electrical contact between the voltage supplying means and the thread.
- the voltage supplying means is also configured to provide a potential between each respective emitter and the thread. This brings an advantage in that it is possible to adjust the potential between the emitter and the thread. This in turn makes it possible to remove electrical charges that ink droplets bring to the thread. Further it makes it possible to at least partly use the thread as an electrode of the counter electrode means. Also, it makes it possible to better attract satellite ink droplets to the thread, thus reducing ink consumption, increasing ink coverage on the thread and reducing contamination of surrounding machine elements.
- the counter electrode is the thread. This brings a further advantage in that no other electrode is needed for the counter electrode means.
- the thread contacting means is configured to contact the thread at a position in which the thread has already passed a discharge zone. This brings an advantage in that electrical charges brought by droplets of ink in the discharge zone will be removed before they distract the droplets from other nozzles along the path of movement of the thread.
- the thread contacting means is configured to contact the thread before it passes the first discharge zone along the path of movement. This brings an advantage in that any electrical charges present on the thread will be removed before it reaches the first discharge zone along its path of movement. This in turn provides for better control of the threads ability to receive ink droplets.
- the coating device is provided with a wetting means configured to make the thread more electrically conductive by application of a wetting agent, such as an electrically conductive liquid.
- a wetting agent such as an electrically conductive liquid.
- a polar wetting agent such as a protic or aprotic polar wetting agent
- a polar wetting agent such as a protic or aprotic polar wetting agent
- a non-polar wetting agent may be selected, such as alkanes, in form of pentane, cyclopentane, hexane, etc.; benzene; toluene; chloroform; diethyl ether; etc.
- these specific wetting agents are also within the ambit of the invention, as long as the wetting agent aims at having the same characteristics as the liquid intended to coat and/or soak the thread.
- the ink-flow controller is configured to operate in a micro dripping mode.
- a flow of ink dispersed in droplets may be achieved, which in turn provides for a good ink coverage on the thread.
- the coating device further comprises a fixation device for fixing non-fixated ink to the thread.
- the fixation device is configured to fix the ink to the thread before non-fixated ink reaches the guiding means after the discharge zone. Thereby, non-fixated ink is prevented from being scraped off the thread when the thread passes a thread guiding means.
- the coating device further comprises at least one treatment device for treatment of the thread before coloring, after coloring, after fixating, or a combination thereof.
- the treatment device may be used singly, separately, or in combination with a coating device and/or thread consuming device, such as a coating device and/or thread consuming device, wherein the thread is coated by means of
- the treatment device is configured to receive the thread after the fixating device. Thereby, the fixating device is prevented from negatively affecting sewability of the thread after the thread has passed the treatment device.
- the treatment device is configured to receive the thread before the electrospraying unit.
- the thread may be pretreated to enhance coloring ability, enhancing sewability, etc., before the thread enters the electrospraying unit.
- the treatment device is configured to wash the thread. Washing of the thread effectively improves sewability of the thread and removes any dust or other unwanted substances present on the thread. Washing may be performed before and/or after the fixating unit, and after coloring.
- the treatment device is configured to lubricate the thread.
- lubricity of the thread is increased, wherein sewability is typically also improved.
- Lubricating may be performed before and/or after the fixating unit, and after coloring.
- an embroidery system comprising a coating device according to an embodiment of the invention. Further, the system comprises thread feeding means, embroidery means and a pattern controller.
- the thread feeding means is configured to feed the thread through the guiding means of the coating device.
- the embroidery means is suitable for embroidering a pattern on an obj ect using the thread based on pattern information.
- the pattern controller provides control signals to said ink flow controller in response to at least the pattern information.
- a method of applying ink to an embroidery thread by means of a coating device comprises a step of feeding the thread through the coating device whilst discharging ink onto said thread using said electrospraying unit.
- the method further comprises a step of wetting the thread before feeding said portion through a discharge zone. Wetting the thread makes it more electrically conductive and typically also improves its ability to quickly absorb ink droplets. Wetting also improves color mixing.
- the method may further comprise controlling the wetting with regards to the amount of the wetting agent used in relation to the thread consumption to achieve a certain color quality (uniformity), better fixation and/or better sewability.
- the method may also comprise controlling the lubrication with regards to the amount of the lubricant used in relation to the thread consumption to achieve a certain color quality (uniformity), better fixation and/or better sewability.
